As the discourse of scientific literacy has broadly summed up the goals of science education in the current decade, this study attempts to question how we contextualize appropriate interpretations and feasible approaches to scientific literacy in K-6 science education. With respect to the complex praxis of scientific knowledge and practice, this study emphasizes the participatory framework of scientific literacy which interweaves children's everyday experiences and science learning. This study also concerns children's abilities to understand and enact scientific enterprises (i.e., children's fundamental sense of scientific literacy). As a way of developing K-6 scientific literacy, this study investigates how using science books can broaden the scope of children's understandings of science in life connections and promote a fundamental sense of scientific literacy through talking, reading, and writing skills in Grade two science classrooms in Canada. Second graders were engaged in learning "sound" for five weeks. During science lessons, children's talks were recorded and their writings were collected for data interpretation. This research finds that using science books can encourage children to become engaged in communicative activities such as talking, reading, and writing in science; furthermore, using science books develops children's inquiry skills. These findings open a further discussion on scientific literacy at the K-6 levels.

The purpose of this research is to know the scientific reasoning ability of elementary students. In order to find it, 320 elementary students wrote a report about germination of the 700 or 2,000 years old seeds. Their writings were analyzed by scientific writing analysis frameworks, Scientific Reasoning Types and Scientific Reasoning Level Criteria developed by Lim (2018). Minto Pyramid Principles was used to show statements and relations of statements related to scientific reasoning. This paper showed scientific reasoning statements of elementary students about germination of seeds. The characteristics of scientific reasoning of elementary students were as follows. In the process of logical writing by the types of scientific reasoning, many students showed various characteristics and different levels. In the writings based on inductive reasoning, they did not distinguish between common features and differences of cases, and did not derive the rules based on common features and differences of the cases. In the writings based on deductive reasoning, there were cases where the major premise corresponding to the principle or rule was omitted and only the phenomenon was described, or the rule was presented but not connected with the case. In the writings based on abductive reasoning, the ability to selectively use the background knowledge related to the question situation was not sufficient, and borrowing of similar background knowledge, which was commonly used in other situations, was very rare.

Scientific reasoning is one of the main concerns in current science education. This study have tried to answer on the question whether Korean science education has the potential to help improve of students' ability to think scientifically. Therefore, the present study investigated the relationship between reasoning patterns evident in science textbook and science examination items, and students' scientific reasoning skills across grades in Korea. 1975 subjects (1022 females and 953 males) were administered in the Lawson's Test of Scientific Reasoning skills. Forty seven science textbooks and 240 assessment instrument were analyzed by several scientific reasoning keys. Scientific reasoning patterns were adopted from Lawson's classification which characterized the patterns as the empirical-inductive and the hypothetical-deductive. This study found that reasoning patterns evident in textbook analyses and assessment instrumental items do not evidentce the potential to stimulate the development of students' reasoning skill. In order to improve the students' abilities to think and achieve, higher levels of reasoning must be included in the science textbook and examination. Further, some of scientific reasoning processes, such as generating hypotheses, designing experiments, and logical prediction, were not found in science textbooks and test items in Korean secondary schools. This study also discussed the educational implication of these results and further studies about to develop student's reasoning ability.

For the quality improvement on private security industry, the quality of personnel in private security should be advanced through the systematic training. If the personnel in private security provide an advanced service in applying knowledge and technique to the field when in training, they can obtain the reliability from people. With the point of this side, practical and systematic training is essential to the restoration on the private security industry. The personnel of private security face many people in the field. So they must work with an active concept that can prevent additional crime from behavior suspicions through scientific observation method and systematic inquiry method rather than negative work with providing a friendly service in the field. For conducting this concept, therefore, this study suggested the improvement training program of "Question and Research Guides" from new employee training on existing private security. The scientific observation standard is specifically suggested from the study 'people watching' of Professor Morris, D. and an act contact question from lead technique that US FBI, police, and inspection institute are taking through the feature of human act and 'METT' that is the program for emotion capture training through human minute look is going to be applied on "Question and Research Guides" training. This will provide the educational mood for students with the training content that is available for the practical training program and the real work, and will help to restore the private security industry with obtaining people's reliability through the scientific work and advanced field treatment.

The purpose of this study was to identify the type of thinking and generating processes of causal questions which were generated in preservice elementary teachers' observing activities. To find the generating processes of causal questions, 4 observing tasks, the task of grapes in soda, the candlelight, the celery, and the rock tasks, were administered to 7 preservice elementary teachers majoring in science education. The results of this study were as follows: The types of thinking in generating explicans exploration questions were classified as 8 types and explicans verification questions were classified as 9 types. The generating processes of explicans exploration questions were classified as 6 steps and explicans verification questions were classified as 5 steps. The results of this study may be used as a teaching strategy for guiding the direction and the method of scientific questions and developing the teaching-teaming programs that help student to generate scientifc questions.

The purpose of this study is to investigate the effect of 'strata-fossils' STEAM program with questions on the academic achievement, creative problem-solving ability and scientific interests of elementary students. For this purpose, the STEAM program with questions was developed and applied to the third and fourth graders in elementary school. As a result, the academic achievement, creative problem-solving ability and scientific interests of the group applying the program showed a significant improvement in the post-test than the pre-test. The result of learner satisfaction survey of the STEAM program was also high. This means that the STEAM program class with questions for 'strata-fossils' could be meaningful works to encourage students' academic achievement as well as their creative problem-solving ability and scientific interests. Therefore, it seems necessary to apply for other themes in elementary science continuously.

In this study, a learning-teaching model enhancing the students to ask questions was developed and the influence of its application to the lesson of 'Chemical Change and Elements' of the 8th grade was investigated. This learning-teaching model was constructed initially by completing the work-sheet to activate student's question-asking, then by writing down their questions or uncertainties in the class, and finally with the feedback of student's question to the individual and to the class. Treatment and control groups (2 classes each) were selected from a girls' middle school in Seoul. and taught for 12 class hours during 4 weeks for this study. Before instruction, the test of attitudes toward science lessons and the test of adoption of scientific attitudes were administered, and the science scores of the previous course were obtained for the covariate. After instruction, the conception test. the achievement test, the test of attitudes toward science lessons, and the test of adoption of scientific attitudes were administered. The TOSRA (Test of Science-Related Attitudes) was used both for the test of attitudes toward science lessons and for the test of adoption of scientific attitudes. The study revealed that the treatment group showed significant differences from the control group in the scores of the conception test (p<.01) and of the achievement test (p<.05). But in attitudes toward science lessons and adoption of scientific attitudes. there were not significant differences between the two groups, even though the scores of the treatment group were a little higher than those of the control group. Educational implications of the effect of science teaching on the questioning activity of students are also discussed.

The present study tested the hypothesis that maturation of the prefrontal lobes is a crucial factor determining the performance of scientific reasoning tasks, Functions of the prefrontal lobes, such as activating relevant information, sequential planning and monitoring, and inhibiting irrelevant information, are related thinking patterns with scientific reasoning. Therefore, we inferred the idea that the prefrontal lobes play an important role in scientific reasoning. To test the hypothesis. the present study investigated a prefrontal lobe patient's task solving procedures in scientific reasoning tasks and the correlation and regression analysis between a test of prefrontal lobe function and two scientific reasoning tasks, The perseverative errors in the Wisconsin Card Sorting Test(WCST) was used as a measure of the prefrontal lobe function, The Melinark Type Task and the Classroom Test of Scientific Reasoning were used as measures of scientific reasoning abilities. Ages and Group Embedded Figure Test were also used as measures of two alternative hypotheses, general maturation and field independency respectively. The prefrontal lobe patient showed a crucial deficiency in solving scientific reasoning tasks. In the tasks, the patient could not used the reasoning of If... and... then... therefore pattern. In correlation study, the perseveration errors of the WCST showed a significantly negative correlation with two scientific reasoning tasks. Multiple regression study also showed that the perseveration errors measured as a function of the prefrontal lobes have more contribution to scientific reasoning ability than contributions of alternative hypotheses. Therefore, the present study supported the hypothesis that prefrontal lobes play a crucial role in scientific reasoning ability, What function of the prefrontal lobes do play crucial role in scientific reasoning? The present study provided an explanation for the question, which inhibiting ability of the prefrontal lobes is responsible for the scientific reasoning ability, in a part at least. That is, perseverative tendency in task-solving procedures causes a deficiency of an ability to inhibit the wrong information to solve a task. The present study provided a possibility of neuropsychological approach in science education research. The present study also showed an importance of the prefrontal lobe development in the performance of scientific reasoning task.

The purpose of this study was to examine the questioning styles in middle school environmentology textbook In terms of frequency, type, and placement of questions. It was also to analyse and to compare the kinds of scientific inquiry processes elicited by the questions in the topics of textbooks. The instrument was the Textbook Questing Strategies Assessment Instrument (TQSAI) developed the Cooperative Teacher Preparation Project, University of California. The average number of Questions per topic was only 1.09 and the ratio of questions to sentences was 2.5%. Most of questions were in explanatory place(75%). Nearly 90% of experienced questions types were reasoning or application. The frequencies of non-experiential question were higher than those of experiential question. In action, there were much kinds of question-styles.

The aims of this study are to investigate two main problems for the hypothetico-deduction method and to develop a scientific inquiry model to resolve these problems. The structure of this scientific inquiry model consists of accounts of the context of discovery and justification that the hypothetico-deduction holds as two main problems : 1) the heuristic flaw in the hypothetico-deduction method is that there is no limit to creating hypotheses to explain natural phenomena; 2) Logically, this brings into question affirming the consequent and modus tollens. The features of the model are as follows: first, the generation of hypotheses using an analogical abduction and the selection of hypotheses using consilience and simplicity; second, the expansion phase as resolution for the fallacy of affirming the consequent and the recycle phase as resolution for modus tollens involving auxiliary hypotheses. Finally, we examine the establishment process of Copernicus's Heliocentric Hypothesis and the main role of the history of science for the historical invalidity of this scientific inquiry model based on three examples of If/and/then type of explanation testing suggested by Lawson (International journal of science and Mathematics Education, 2005a, 3(1): 1-5) We claim that this hypotheticho-deduction process involving abduction approach produced favorable in scientific literacy rising for science teacher as well as students.
